Epidemiology of child psychopathology: major milestones

Associations between negative gender attitudes and eating behaviors in Chinese children and adolescents

Background

Negative gender cognitive attitudes (disliking one's own gender or wanting to be the opposite gender) and unhealthy eating behaviors have become common in Chinese children and adolescents. The aim of this study was to analyze the associations between negative gender attitudes and eating behaviors among Chinese children and adolescents.

Methods

Primary and secondary school students aged 8-15 years were selected as participants using a stratified cluster random sampling method. The self-designed questionnaire was used to investigate the participants' negative gender cognitive attitudes. Eating frequency questionnaire was used to investigate participants' eating behaviors. Under the leading reading of standardized training investigators, the questionnaire for children aged 8-15 years was completed by themselves in the form of centralized filling.

Results

A total of 6.5% [43/657, boys: 6.1% (21/347), girls: 7.1% (22/310)] of children disliked their own gender, 8.8% [58/657, boys: 5.5% (19/347), girls: 12.6% (39/310)] of children wanted to be of the opposite gender, and the proportion of girls with negative gender attitudes was higher than that of boys (P < 0.05). Boys who disliked their own gender or wanted to be the opposite gender had higher frequencies of unhealthy eating behaviors and lower frequencies of healthy eating behaviors than boys who liked their own gender or did not want to be the opposite gender (P < 0.05). Girls who disliked their own gender or wanted to be the opposite gender had higher frequencies of protein eating behaviors than girls who liked their own gender or did not want to be the opposite gender (P < 0.05). There was a significant interaction between disliking one's own gender and wanting to be the opposite gender in midnight snack eating among boys (P < 0.05) and in carbonated drink and high protein eating behaviors among girls (P < 0.05).

Conclusion

Boys with negative gender cognitive attitudes express more unhealthy eating behaviors and fewer healthy eating behaviors; girls with negative gender cognitive attitudes exhibit more protein eating behaviors.

General Anxiety, Diabetes-Specific Anxiety, and Quality of Life in Adolescents With Type 1 Diabetes

PURPOSE

The purpose of the study was to identify the differential associations between general anxiety, diabetes-specific anxiety, and diabetes-specific quality of life (QOL).

METHODS

A cross-sectional study was conducted of 146 adolescents with type 1 diabetes (T1DM) ages 13 to 17 during the COVID-19 pandemic. Participants completed self-report questionnaires assessing demographic characteristics, general anxiety, diabetes-specific anxiety, depressive symptoms, and diabetes-specific QOL.

RESULTS

The final sample of 146 adolescents was mostly male, non-Hispanic White, mean age of 14.5 ± 1.27, having diabetes for more than 1 year, and using insulin pumps. Higher diabetes-specific anxiety was associated with poorer general treatment-related QOL, but general anxiety was not. General anxiety, diabetes-specific anxiety, and depressive symptoms were significantly associated with diabetes-specific treatment-related QOL, worry-specific QOL, and poorer communication-related QOL.

CONCLUSIONS

There may be a differential impact of general anxiety and diabetes-specific anxiety in adolescents with T1DM. Diabetes-specific anxiety may be a more important factor in adolescents reporting poorer general treatment-related QOL, worry-related QOL, and communication-related QOL, while general anxiety and diabetes-specific anxiety appear to similarly impact poorer diabetes-specific treatment-related QOL. Diabetes-specific anxiety may be a more important component of QOL in adolescents. Targeted interventions may be required to effectively improve QOL.

The importance of selection bias in prospective birth cohort studies

Sophisticated statistical analyses of data from large-scale prospective birth cohort studies combined with thoughtful study designs have advanced understanding about the causes, consequences and developmental course of child and adolescent mental health problems. Available large-scale prospective cohort studies, such as ALSPAC, MoBA, and TEDS have many noteworthy strengths, but they all suffer from non-random non-participation and attrition over time. Recent findings have highlighted that prospective birth cohort studies need to carefully consider the importance of selection bias.

The Behavior and Mind Health (BeMIND) study: Methods, design and baseline sample characteristics of a cohort study among adolescents and young adults

OBJECTIVES

The Behavior and Mind Health (BeMIND) study is a population-based cohort study of adolescents and young adults from Dresden, Germany. The aim is to investigate psychological and behavioral factors linked to a range of mental disorders and health behaviors and their interaction with social-environmental and genetic/biologic factors.

METHODS

A random sample of 14-21 year olds was drawn from the population registry in 2015. The baseline investigation was completed 11/2015-12/2016 (N = 1,180). Assessments include standardized diagnostic interview, cognitive-affective tasks, questionnaires, biosamples, and ecologic momentary assessment in real life with combined actigraphic/geographic monitoring. In the family study component, parents completed similar assessments and provided information on child's early development.

RESULTS

The participation rate (minimum response proportion) was 21.7%; the cooperation rate was 43.4%. Acceptance and completion of study components were high. General health data indicate that more than 80% reported no or only mild impairment due to mental or somatic health problems in the past year; about 20% ever sought treatment for mental health problems or chronic somatic illnesses, respectively.

CONCLUSIONS

Data from BeMIND baseline and follow-up investigations will provide novel insights into contributors to health and disease as adolescents grow into adulthood.

State and Trait Anxiety and Diabetes Outcomes in Youth With Type 1 Diabetes

PURPOSE

The purpose of this exploratory pilot study was to examine the associations of state and trait anxiety with glycemic control, self-management, and diabetes-specific quality of life (QOL) in youth 10 to 16 years of age with type 1 diabetes (T1D).

METHODS

Bivariate Pearson correlations and multiple linear regression modeling were conducted to examine the relationship among anxiety symptoms, hemoglobin A1C (A1C), self-management, QOL, and covariates.

RESULTS

A sample of 67 adolescents was 50.7% female, and 87.1% were non-Hispanic white, with a mean ± SD age of 13.4 ± 1.85 years and an A1C of 8.3% ± 1.2% (67 mmol/mol). Higher state anxiety was correlated with older age. Better self-management was correlated with lower trait anxiety and lower state anxiety. Higher state and trait anxiety were associated with poorer self-management. Higher state anxiety was associated with higher A1C. Higher trait anxiety was associated with poorer diabetes-specific QOL.

CONCLUSIONS

State and trait anxiety may differentially affect diabetes outcomes. State anxiety may be a modifiable target for physiologic (A1C) and psychosocial (QOL) outcomes in youth with T1D, while trait anxiety may be a modifiable target for psychosocial outcomes (QOL). Anxiety symptoms should be assessed at regular clinic visits. Interventions to improve anxiety symptoms may in turn improve physiologic and psychosocial outcomes.

Psychiatric disorders in adolescents with type 1 diabetes: a case-control study

Objectives:

To study the prevalence of psychiatric disorders in adolescents with and without type 1 diabetes, the factors associated with its presence, and to test the reliability of a screening tool for use in clinical settings.

Methods:

Eighty-one adolescents were enrolled in this case-control study, including 36 diabetic participants and 45 controls. Clinical and sociodemographic data were collected and psychiatric symptoms and diagnoses were obtained from adolescents and their parents using a screening tool (Strengths & Difficulties Questionnaire) and a semi-structured interview (Development and Well-Being Assessment).

Results:

Psychiatric disorders were identified in 22.2% of the sample (30.56% among diabetic adolescents vs. 15.56% of controls: OR = 2.39, 95%CI 0.82-6.99; p = 0.11). Overweight (body mass index percentile ≥ 85) was the only factor associated with psychiatric disorder (OR = 3.07; 95%CI 1.03-9.14; p = 0.04). Compared to the semi-structured interview, the screening instrument showed 80% sensitivity, 96% specificity, 88.9% positive predictive value and 92.3% negative predictive value for the presence of psychiatric diagnoses in adolescents.

Conclusion:

Psychiatric morbidity was high in this sample of adolescents, especially among those with diabetes. Routine use of the Strengths and Difficulties Questionnaire can help with early detection of psychiatric disorders in this at-risk group.

Are the time trends in adolescent psychosomatic problems related to functional impairment in daily life? A 23-year study among 20,000 15-16year olds in Sweden

OBJECTIVE

Worldwide there are frequent reports on increasing psychosomatic problems, anxiety, emotional distress, conduct problems, and depression among adolescents. Recently, it was contended that secular studies on such aspects of adolescent mental health can only be evaluated adequately when data on symptom prevalence are analyzed together with data on functional impairment. Still, this has not yet been done in epidemiological time-trend studies on any aspect of adolescent mental health. Therefore, this study aims to investigate if, and to what extent, changes in adolescents' symptoms of psychosomatic problems are affected when data on functional impairment are taken into account simultaneously.

METHODS

A repeated cross-sectional population study relating self-reported symptoms of psychosomatic problems to functional impairment; covering the time-period 1988-2011 and including 19.823 adolescents 15-16years old in eight cohorts in one geographically defined population (Värmland, Sweden).

RESULTS

The proportion of adolescents with psychosomatic problems had increased significantly from 1988 to 2005/2008. In all cohorts the proportion of girls with psychosomatic problems was significantly higher than the proportion of boys reporting symptoms. Over the same period, there was a corresponding significant increase of the proportion of participants with symptoms of psychosomatic problems in combination with functional impairment. Adding functional impairment to the measure of psychosomatic problems decreased the prevalence rates, while the shapes of the trend-curves stayed congruent in form.

CONCLUSION

The long-term pattern of increasing psychosomatic problems among adolescents remains evident, even when taking functional impairment data into account. Previously observed trends of a deteriorating adolescent mental health are thus consistent with this study.
